@schemeless/event-store-react-native/src/operators/defaultEventCreator.ts

React Native compatible build of the [`@schemeless/event-store`](../event-store) runtime. It mirrors the Node.js implementation but swaps the internal queue implementation to [`react-native-better-queue`](https://github.com/YahyaASadiq/react-native-better

  return typeof date === 'string' ? new Date(date) : date;
